MR-conditional Robotic Actuation of Concentric Tendon-Driven Cardiac Catheters [PDF]
arXiv, 2023 Atrial fibrillation (AF) and ventricular tachycardia (VT) are two of the sustained arrhythmias that significantly affect the quality of life of patients. Treatment of AF and VT often requires radiofrequency ablation of heart tissues using an ablation catheter.

Force‐sensing catheters during pediatric radiofrequency ablation: The FEDERATION Study [PDF]
, 2017 Background Based on data from studies of atrial fibrillation ablations, optimal parameters for the TactiCath (TC; St. Jude Medical, Inc) force‐sensing ablation catheter are a contact force of 20 g and a force‐time integral of 400

Neural Network Reconstruction of the Left Atrium using Sparse Catheter Paths [PDF]
arXiv, 2023 Catheter based radiofrequency ablation for pulmonary vein isolation has become the first line of treatment for atrial fibrillation in recent years. This requires a rather accurate map of the left atrial sub-endocardial surface including the ostia of the pulmonary veins, which requires dense sampling of the surface and takes more than 10 minutes.

A computational model of open-irrigated radiofrequency catheter ablation accounting for mechanical properties of the cardiac tissue [PDF]
, 2018 Radiofrequency catheter ablation (RFCA) is an effective treatment for cardiac arrhythmias. Although generally safe, it is not completely exempt from the risk of complications. The great flexibility of computational models can be a major asset in optimizing interventional strategies, if they can produce sufficiently precise estimations of the generated ...

Ultrasonic characterization of the pulmonary venous wall: echographic and histological correlation [PDF]
, 2002 Background: Pulmonary vein isolation with radiofrequency catheter ablation techniques is used to prevent recurrences of human atrial fibrillation. Visualization of the architecture at the venoatrial junction could be crucial for these ablative techniques.

A worldwide survey on incidence, management and prognosis of oesophageal fistula formation following atrial fibrillation catheter ablation: The POTTER-AF study. [PDF]
, 2023 AIMS Oesophageal fistula represents a rare but dreadful complication of atrial fibrillation catheter ablation. Data on its incidence, management and outcome are sparse. METHODS AND RESULTS This international multicenter registry investigates the

Shortness of breath after AV ablation: case of left phrenic nerve palsy [PDF]
Journal of Community Hospital Internal Medicine Perspectives, 2013 Phrenic nerve palsy has been recognized as a complication of catheter ablation with a prevalence of 0.11–0.48% after atrial fibrillation ablation, independent of the type of ablation catheter or energy source, likely due to the anatomical ...
